Definitions

  • This invention relates to pull-out folding sofa beds.
  • One object of this invention is to provide a bed having a foot section which is softer and more resilient at the sides thereof, when the bed is in folded or closed position, for use as a sofa.
  • the mattress supporting fabric has been connected to the side portions of the foot section of the folding bed, by a relatively large number of helical springs, (such as eight helicals). Furthermore the side portions of the foot section heretofore were in the plane of the mattress supporting fabric. Such prior constructions often made it uncomfortable to sit on the sofa near the side arms of the sofa frame, or even therebetween, because there was too much tension on the mattress supporting fabric, and the side portions of the foot section were at the level of the foot section frame.
  • Still another object of this invention is to provide in a bed of the character described, a mattress supporting fabric which is connected to each side of foot section frame only by a pair of helical or coil tension springs instead of by more helical springs, as is common in prior constructions.
  • a further object of this invention is to provide a bed of the character described, in which the end arms of the zig-zag springs are received in the helical tension springs which attach the mattress supporting fabric to the side arms of the foot section, to house and encase said end arms.
  • Yet a further object of this invention is to provide a strong, rugged and durable bed construction of the character described which shall be relatively inexpensive to manufacture, easy to assemble, comfortable in use and which shall yet be practical and efficient to a high degree.
  • FIG. 1 is a top plan view of a folding bed mattress supporting platform for a pull-out sofa bed, embodying the invention
  • FIG. 2 is a perspective view of the foot section of such bed, with parts broken away;
  • FIG. 3 is a side elevational view of the platform in folded condition
  • FIG. 4 is a partial side elevational view of the rear end of the platform shown in FIG. 1.
  • FIG. 10 designates a mattress supporting platform embodying the invention.
  • This platform is part of a folding pull-out sofa bed in which the platform, when in open or sleeping position is extended in a horizontal plane and is attached by leverage (not shown) to a sofa bed wood frame (not shown), in the well known manner.
  • Said bed platform 10 comprises a rear head section 11 pivoted as at 12 to a first or intermediate long section 13 which in turn is pivoted as at 14 to a short or second intermediate section 15 pivoted as at 16 to a front foot section 17.
  • This platform is provided with front and rear legs (not shown), but of usual, well known construction.
  • the invention herein resides in the construction of the foot section and its connection to the mattress supporting fabric 20.
  • the head section 11 may be of usual construction and comprises a pair of parallel, similar, symmetrical side arms or angles 11a interconnected by a rear cross-tube 11b and is connected to mattress supporting fabric 20 of usual construction except as described hereinafter, and including linkage connected to the side angles 11a by coil or helical tension springs 22, and by links 23, to the cross member 11b.
  • the first or long intermediate section 13 comprises parallel, symmetrically disposed side angles 13a connected to part of the fabric 20 by coil or helical springs 24.
  • the short or second intermediate section 15 comprises short similar, symmetrical side angles 15a connected to the fabric by helical tension springs 25.
  • the foot section 17 may be made of tubular stock and comprises a front cross-tube 17a from which similar, symmetrical side arms 17b extend rearwardly, when the bed is in the open, sleeping position of FIG. 1.
  • Said side arms 17b may be of tubular stock, die pressed into angular shape to have bottom inwardly extending flanges 17c and outer, upwardly extending vertical flanges 17d, when the bed is in the open sleeping position of FIG. 1.
  • said arms 17b were straight. Also said straight side arms of prior constructions were usually each attached directly to the mattress supporting fabric by many helical tension springs.
  • the long intermediate section 13 is at the bottom, the rear head section projects up from the rear end of said long intermediate section; the short intermediate section 15 projects vertically upwardly from the front end of the long intermediate section 13, and the foot section 17 projects rearwardly from the upper end of the short intermediate section and overlies the long intermediate section 13, in vertically spaced relation thereabove.
  • the usual mattress (not shown) is at least partially disposed between sections 13 and 17 when the bed is folded.
  • the sofa pillows (not shown) are placed on top of the rearwardly extending foot section 17, when the bed is fully collapsed in sofa position.
  • portions 17e of the side arms 17b of the foot section herein are raised, between the ends of said side arms, (in the sleeping, open or extended position of the bed) as shown in FIGS. 1 and 4 of the drawing.
  • the raised portions 17e are major lengths of the side arms.
  • Said side arms have rear end portions 17f adjacent the cross bar 17a, and front end portions 179 adjacent the pivots 16 (when the bed is in open, sleeping position).
  • portions 17e are longer than the portions 17f and 17g. Between portions 17e and portions 17f are shoulders 17h. Between portions 17e and portions 17g are shoulders 17i.
  • the mattress supporting fabric 20 includes transverse links 20a hooked or connected to longitudinal links 20b in usual manner. At the junctions of the transverse links 20a, with the end rows of longitudinal links 20b are loops 25 connected by converging links 20c, 20d joined at apex loops 20 e and forming triangles, as shown in the drawing.
  • a helical tension spring 30 is hooked at one end to a hole 31 in portion 17g and at its other end to loops 20e at the junction of links 20c, 20d.
  • a second helical tension spring 33 is hooked at one end in a hole 34 in portion 17f and at its other end to similar loops 20e of another triangle of links, similar to links 20c, 20 d.
  • each side arm is a zig-zag spring 40 having end arms 41 received in helical or coil springs 30, 33.
  • a pair of triangles 20b, 20c, 20 d similar to the aforementioned pair of triangles, and disposed therebetween have their apeces attached by clips 45 to inwardly extending bends in the zig-zag spring 40 located inwardly of the outer end arms of the zig-zag spring.
  • a pair of outwardly extending bends 46 of said zig-zag springs 40 are connected by clips 47 to ends of portions 17e of the side arms 17b of the foot section. The bends 46 are located just inwardly of the helicals 30, 33.
  • the mattress supporting fabric is attached directly to each of the side arms by only two helical springs instead of a larger number provides for a more resilient, more flexible, more relaxed seat throughout the length of the sofa.
  • the zig-zag springs 40 provide soft edges at the ends of the foot section, for the purpose of creating softer, more depressible seats when the bed is in use as a sofa.
